电动硬密封蝶阀工作原理

2013-1-15 11:59:19      点击:
 工作电源通常有:AC220V AC380V等。 输入信号:4~20mA 0~10v等弱电信号。 由调节型电动执行机构和阀杆连接调试好以后;以电能作为驱动力来驱动硬密封蝶阀阀板,作0~90°部分回转运动。 接收工业自动化控制系统的4~20mA信号来精确控制阀门开度,从而达到流量、温度、压力等不同工艺参数的调节和控制。 硬密封蝶阀的驱动形式除了电动之外还有:手动,蜗轮杆传动,气动等。 阀门的连接形式有无法兰对夹式,法兰连接和对焊连接.

Electric hard seal butterfly works Usually working power: AC220V supply AC380V, and so on. Input signal: 4 ~ 20mA, 0 ~ 10v, such as weak signal. Good debugging; by modulating electric actuator and valve stem connected to the electrical energy as the driving force to drive the hard seal butterfly valve plate for 0 ~ 90 ° part of the rotary movement. 4 ~ 20mA signal receiving industrial automation control system to precisely control the valve opening, so as to achieve the regulation and control of the flow, temperature, pressure and other process parameters. Hard sealing butterfly valve drive form outside in addition to electric there: Manual, worm gear lever transmission, pneumatic. The form of the connection of the valve with or without flange Wafer, flanged and butt weld connections.
